Extract state.bin from the zip file, and upload it to/var/mobile/Documents/ use OpenSSH
Change the permission of state.bin to 644 or 0644 depends on the SSH client you are using (if the previous number is 3 digits use 644, 4 digits use 0644)
If it doesn’t work, copy state.bin to /user/Documents/, and also change the permission.
